INTRODUCTION

What is soy lecithin? Lecithin is a food additive that comes from several sources – one of them being soy. It’s generally used as an emulsifier, or lubricant, when added to food, but also has uses as an antioxidant and flavor protector.

Soy lecithin is composed of choline, fatty acids, glycerol, glycolipids, phospholipids, phosphoric acid and triglycerides.

The diverse forms in which lecithin is available – fluid, powder and granules – make it even more suitable to use as per industry specific demands. With additional processing, fluid lecithin can also be hydrolysed, fractionated, hydroxylated and acetylated for very specific industry applications.

Manufacture

Soy Lecithin is made from fresh gums, during de-gumming of Soybean Oil obtained from Soybean seeds.

CAS no.8002-43-5, 8030-76-0
EINECS no.232-307-2
Molecular formulaC42H80NO8P
Molecular weight643.9

Applications

It is used in human food, pharmaceuticals, animal feed, paints, and other industrial applications.

In food industry as an emulsifier, stabilizer, lubricate, release agent, antioxidant and dispersant.
In the pharmaceutical industry, it acts as a wetting agent, stabilizing agent and a choline enrichment carrier, helps in emulsification and encapsulation, and is a good dispersing agent. It can be used in manufacture of intravenous fat infusions and for therapeutic use.
In animal feed, it enriches fat and protein and improves pelletization.
In the paint industry, it forms protective coatings for surfaces with painting and printing ink, has antioxidant properties, helps as a rust inhibitor, is a color-intensifying agent, catalyst, conditioning aid modifier, and dispersing aid; it is a good stabilizing and suspending agent, emulsifier, and wetting agent, helps in maintaining uniform mixture of several pigments, helps in grinding of metal oxide pigments, is a spreading and mixing aid, prevents hard settling of pigments, eliminates foam in water-based paints, and helps in fast dispersion of latex-based paints.
Also, may be used as a release agent for plastics, an anti-sludge additive in motor lubricants, an anti-gumming agent in gasoline, and an emulsifier, spreading agent, and antioxidant in textile, rubber, and other industries.
